Background: Although bone mineral density is reported to be increased in patients with postsurgical hypoparathyroidism (postsurgical HypoPT), the effect of HypoPT on trabecular bone score remains unknown. This study evaluated the long-term effects of HypoPT secondary to total thyroidectomy for differentiated thyroid cancer on trabecular bone score, bone mineral density, and bone turnover markers with a similar group of patients without HypoPT.
Methods: Women with resected differentiated thyroid cancer and either postsurgical HypoPT (n = 25; 8 premenopausal and 17 postmenopausal) or euparathyroid function (n = 98; 14 premenopausal and 84 postmenopausal) were matched for age and body mass index. Patients received thyroid-stimulating hormone suppression during follow-up. The bone mineral density and trabecular bone score were analyzed using dual x-ray densitometry and Med-Imaps software at baseline (1-3 months postsurgery) and at the final study visit.
Results: Follow-up duration was similar in studied groups (median 10 years). Baseline bone mineral density and trabecular bone score were similar between HypoPT and non-HypoPT patients, regardless of menopausal status. At study end, postmenopausal HypoPT patients had greater bone mineral density versus the non-HypoPT patients at the lumbar spine, hip, and distal radius (P = .001), and a greater trabecular bone score (1.31 ± 0.09 vs 1.24 ± 0.12, P = .0184). Premenopausal patients with and without HypoPT had similar bone mineral density values at the final evaluation. The bone turnover markers (osteocalcin, bone-specific alkaline phosphatase, and β-crosslaps) were less in postmenopausal HypoPT patients, reflecting decreased bone turnover.
Conclusion: Postmenopausal patients who underwent a total thyroidectomy for differentiated thyroid cancer with postsurgical HypoPT have greater trabecular bone score and bone mineral density compared with euparathyroid patients, suggesting that HypoPT protects against the negative effects of long-term thyroid-stimulating hormone suppression treatment on bone.

Limited whole genome sequencing (WGS) studies in Asian populations result in a lack of representative reference panels, thus hindering the discovery of ancestry-specific variants. Here, we present the South and East Asian reference Database (SEAD) panel ( https://imputationserver.westlake.

Introduction: Diabetes mellitus (DM) is a chronic metabolic disorder that increases fragility fracture risk. Conventional DXA-based areal bone mineral density (aBMD) assessments often underestimate this risk. Cortical Backscatter (CortBS) ultrasound, a radiation-free technique, non-invasively analyzes cortical bone's viscoelastic and microstructural properties.

Background: Previous studies have shown that bone mineral density (BMD) has a certain impact on scoliosis. However, up to now, there is no clear evidence that there is a causal association between the two. The aim of this study is to investigate whether there is a causal association between BMD at different body positions and scoliosis by two-sample Mendelian randomization (MR).

Purpose: To assess bone mineral density (BMD) in middle-aged individuals in Shanghai, in order to improve awareness of osteopenia and osteoporosis screening.
Methods: The clinical data of 1107 permanent residents of Shanghai aged 40-60 years were collected using a random cluster sampling method. Osteoporosis questionnaire survey and BMD test were conducted.

Purpose: The goal of this cross-sectional study was to investigate the prevalence of vitamin D deficiency in young orthopedic trauma patients and its impact on bone mineral density (BMD) measured through computed tomography imaging of the lumbar spine.
Methods: Conducted at a level I trauma center, this prospective cross-sectional analysis included 100 patients aged 18 to 50 years with non-fragility fractures. Vitamin D levels and Hounsfield units of the lumbar spine were recorded from computed tomography scans.
